Description:
Very recent data for the reaction gammad-->etanp, namely, total cross sections, angular and momentum spectra, are analyzed within a model that includes contributions from the impulse approximation and next-order corrections due to the np and etaN interactions in the final state. Comparison between the calculations and the new data indicate sizable contributions from the np and etaN final-state interactions. Some systematic discrepancies between the calculations and the data are also found.
